IMPROVEMENT IN WATER-CLOSET VALVES.

Specification formingpart of Letters Patent No. 175,035, dated March 21, 1876; application filed' February 26, 1876.

To all whom lit may conce/rn Be it known that I, THOMAS CONAUGHTON, of New York, in the county of New York and State of New York, have invented a new and valuable Improvement in Water-Closet Valves; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part ot' this specification, and to the letters and figures of' reference marked thereon.

Figures 1 and 2 ofthe drawings are representations of vertical central sections of my valve.

This invention has relation to valves which are designed for water-closets, but which are applicable to other purposes; and the nature of my invention consists in the combination,A with a spherical shell, having inlet and outlet passages for water and air, and a push-stem, of' an elastic ball, whichis hollow, and which is perforated just below the airvalve, as will be hereinafter explained.

The invention also consists in a hollow spherical iioat in combination with a perforated spherical valve and a spherical shell having an air-vent at its upper part, said tloat being inside of the valve, and intended to shut the air-vent should the valve burst, as will be understood from the followingdescription The metal case ot' my improved valve is spherical and composed of. two parts, A A', screwed together, as shown in Fig. 2. The bottom section A is constructed with a screwthreaded inlet-pipe, a, and a screw-threaded outletpipe, a; also, with a standard, b, which is screw-threaded and adapted to receive a valve, c, the stem o of which may be any desired length.

The upper section A of the case is vperforated at d, which perforation is surrounded externally by a prismatic valve-box, C, perforated at several points, and having screwed upon it a removable cap, e, constructed with a nuthead to receive a wrench, and a stud, f, on its under side, which is loosely inserted into a hole made in the stem of a valve, D, which closes the opening d. This valve D has a very line perforation, t', through it, which admits air into a spherical valve, E, when the valve D is shut. y

Valve E is a hollow sphere made of indiarubber, and preferably constructed with a packing-flange,j, which seals the joint between the sections AA of the case;V At' the highest part ot' the valve E is an opening, d', which registers with the opening d through the case, and which is designed for the exit and admission ot' air.

Inside of the valve E is a hollow spherical ioat4 G, which will rise and shut the openings d d should the valve E burst.

When the stem o of valve o is forced up, as shown in Fig. 1, a passage will be Opened through the valve-case for water, and when the stem o is released the pipes a a will be shut by the expansion of the valve E.

What I claim as new, and desire to secure by Letters Patent, is-

1. The sectional spherical valve-case A A', constructed with water inlet and outlet a a', and with an inlet and Outlet valve D, and a valve, o, in combination with the perforated elastic spherical valve E, substantially as described.

2. The spherical iioat G, combined with a valve constructed and operating substantially as described.

In testimony that l claim the above I have hereunto subscribed my name in the presence of two witnesses:

THOMAS CONAUGHTON.
